So, here’s my little advice, which comes from quite a lot frequentations in Italian BarCamps. Do you want to promote yourself? Fine, everyone wants.
Then don’t be afraid to take the microphone (if any) and start sharing ideas. Don’t talk about your project. Nobody cares. Instead, share a new idea, a point of view, explain why you believe in it. And, guess what? People will start thinking “how cool!”. They will talk to you after the speech, asking for more information.
